Abstract
Official abstract text for this publication.
The present invention provides a light guide plate and a manufacturing method thereof. The light guide plate includes a light guide plate body and ink dots printed on a surface of the light guide plate body. The ink dots contain an antistatic agent. The manufacturing method of the light guide plate includes (1) providing a light guide plate body; (2) providing an ink and an antistatic agent ad mixing the antistatic agent in the ink; and (3) printing the ink that contains the antistatic agent on a surface of the light guide plate body to form the ink dots. The antistatic agent contained in the ink dots helps suppressing static electricity generated on the light guide plate so as to eliminate mura caused by electrostatic attraction.
